Arithmetic Operations Addition Subtraction-3-2 Multiplication*3*6 Right Division/7/3 Left Division\7\3 = 3/7 Exponentiation^2^3 = 8

Precedence Precedence is the order operations are preformed (3^2) anything in parentheses is done first 5^2 exponentiation is next 2*2 or 10/5 multiplication or division next 1+1 or 5-3 addition or subtraction next Operations are done from left to right

Precedence Example 2^(6/2) = 2^3 = 8 2^6/2 = 64/2 = 32

Some Syntax Assignment operator = > x= 1; > x = 2*x+1; The value of x is 3 not -1 ;

Predefined Variables ans pi  eps2^(-52) about 2.22e-16 inf  isqrt(-1) jSame as i NaNNot a number 0/0

Some Functions Elementary Math, sqrt(x), exp(x), etc. Trig, sin(x), cos(x), x is in radians Rounding functions, round(x), etc
